Generic V-shape tuning with middling technicalities. Crin Youtube Channel
Truthear Zero: Blue 2 Reviews
Pros: Slightly more balanced and pleasing Harman tuned. Cons: Treble with silicone tips is piercing. Tim Tuned Youtube Channel
Harman target tuned. Sounds pretty V and contrasty. Not a whole lot of mids. Fairly tasteful. Good sense of separation. Sterile/Lifeless mids and annoying treble. Needs foam eartips.Super* Review original ranking

Fun sub-woofer sound in the low-end, nice bouncy textue, but uppermids/treble can be too bright, especially with 15K treble peak. Basically a more v-shaped version of the OG TE Zeros. Vocals can be a bit shouty and thin. Jays Audio Youtube Channel
Harman tuning with clean, punchy bass and great resolution. Bright treble.Gizaudio Axel original ranking

BASS With the adapter this goes up a bit, but it is difficult to recomend. Jaytiss Youtube Channel
